PCs serial communications, data reception and transmission of the source

用FPGA实现RS232，代码经过测试通过-FPGA implementation using RS232, the code has been tested through

I2C端口设计,由ASM设计完成,实现I2C端口功能-I2C port design, the design completed by ASM, I2C port functions

一个串口测试程序，包括源代码，供大家学习-A serial test procedure, including the source code for everyone to learn

我用VC编的一个小小的串口应用程序,里面用到了一个库CComm。挺简单的。-I VC series a tiny serial applications, they use a library CComm. Very simple.

从串口读取数据，有两种方法， 1、每接收一个EV_RXCHAR,就用ReadFile读一次，这样我觉得太恐怖了。 2、接收到一个EV_RXCHAR后，等一定数据量的CPU周期(GetTickCount),再一次性读取缓冲区里的数据。这样做，一般情况下不会有问题，但是，如果数据很多，过了“一定数据量的CPU周期”，还没收完数据怎么办？就会少读数据了。 我用三个线程序来完成串口数据的-read data from the serial port, there are two methods, one, each receiving a EV_RXCHAR, on the ReadFile read, I think this vote. 2, received a EV_RXCHAR after a certain volume of data, such as CPU cycles (GetTickCount), and the one-time reader, the data buffer. To do so, under normal circumstances there is no problem, but if many of the data, and after a "certain amount of data the CPU cycles," also confiscated End Data how do? Few will read the data. I used three lines to complete serial data

下面是串口通信开发的部分原码,自己写的,可能有些错误,希望大大家指教.-Below is a serial communication part of the original development of the code, wrote it myself, may be some mistakes and we hope that the shortage.
